Most of Cyril was built recently: 9% of its homes predate 1940 and the median home dates from 1968. Below: maps from 1949 on and the census since 1920.
On August 25, 1901, Louise (probably called Cyril) Lookingglass, the infant daughter of Bayard (Monapahrah) and Laura (Tit-tah-ter-way) Lookingglass, was allotted 160 acres (0.65 km2) of land that would become the Cyril townsite. Louise Lookingglass died in 1903. Bayard Lookingglass sold one-half of the allotment to Mr. and Mrs. Pierson on July 26, 1907. The Piersons sold the land to the Cyril Townsite and Development Company on September 10, 1907.
